Our invention relatesto baling presses and more'partlcularly to power "drlven presses and is a continuation of application of Theodore Williams, Hermann Hill and Clarence A. Swart, Serial No. 557,890, filedMay' 2,

The object of our invention, is to provide means forswinging the baling plungerpi platen clear of the top of the baling chamber, thus permitting loading or chargingof the baling' chamberv from the top thereof.

In the accompanying drawings forming part of this specification: v

Figure 1 is a side elevation of the baling press embodying ourf invention showing the plunger in full lines in vertical position at one side of the baling chamber, and dotted lines inhorizontal position within the baling chamber; a r. a v v Figure 2 is an end view of the press looking at the motor end thereof, the plunger member being shown-in dotted lines, in loweredhorizontal position within the'baling chamber; j l a Figure 3 is a horizontal, sectional View through the baling chamber; I Figure 4 is a detail sectionalview showing the position of the plunger bar when the plunger member is in lowered horizontal position within the baling chamber; and

Figure 5 is a detail view showing the pitmen and plunger bar'connection.

Referring more particularly to the drawings wherein like referencenumeralsdenote corresponding parts throughout the several views, 1, represents a base comprising a'bedj plate 2, in the form of asteel casting, adapted to rest upon the spaced I beams 3 and.

4. A plurality of short transverse slats 5, which rest upon and are suitably connected to the bed plate, form the platen of the baling chamber, to be referred to, hereinafter;

Resting upon and suitably secured to the slats 5, as by braces 18, is a baling chamber 6, the end walls 7 and Set which each comprise two metal plates 9 and 10 respectively.- The side walls 11 and12each comprise a single plate 12 and 13 jhingedly connected to the plates 10, of the end wall 8, as at 14 and 15 respectively to permit of access to the baling chamber from the sides thereof. The plates of each end wall are spaced apart at for connection and bracing the plates of. the v respective end walls.

The bed plate 2, is formed at opposite ends W with bearings 20 and-21 preferably cast integral therewith in which vertical screws 22 and 23 are rotatably mounted. Connected to the lower extremities, of the respective screws are large bevel gears 25 and 26,1nesh ing withbevel pinions 27 and 28 fined to opposite ends of the horizontal shaft 29, in turn rotatably mounted in brackets 30 and 31 securedto the bottom of thebed plate 2. qt:- A spur gear 32, fixed on that end of the shaft 29, to which; the pinion 28, is secured meshes with the pinion 33,0n the drive shaft 34 of the motor 35. i v

The piston or plunger member of the press comprises what may be termed a plunger bar 36. This plunger bar is preferably formed of two strips or members 3'? and 38 having Offset extremities 39 and 410, thus in effect forming a plunger bar with forked "2i, ends when the intermediate portions of the aforesaid strips ormembers 37 and 38 are placed injuntaposed position as illustrated in Figure 4. lit will of course, be understood that the bar 36, may be formed Of'a single casting having forkedends. Suitably secured to the bar 36, by any means (not shown) is a steel plate 39', to the bottom face of which slats 40, similar to the slats 5, are: bolted, as at 4:1. This entire piston or plungermember is supported by two pair of pitmen rods 42 and 43,'which are secured to and carry at their upper or outer free ends trunnion heads 44 and 45, which the forked ends of the plunger bar 36 embrace and to which they are bolted or otherwise suitably secured. The opposite or lower ends of the pitmen rods are journaled on the trunnions 46 and 47 of nuts 51 and '52 in turn threaded-- ly mounted on the respectivescrews 22 and 23, the nuts being free to move up and down upon the screws when the latter are turned, but are locked against turning movement by reason of their engagement with, the pairs of oppositely disposed guide strips bar. spans the baling chamber, .the forked- 53 and 54; secured to the respective brackets 90 and 90; Thestrips 53 and 54 enter oppositely disposed recesses and 56 in the jrespectivenuts, the latter being free to slide upamdxlownwjth respect to the said strips.

. .ThBTdIlTBIHlQCllalEB'TTPGITtlOD of plunger end of the bar projecting out through the slots 16 and 17 on opposite ends or the ham r-4. u It will be understood that simultaneous rotation of the screws 22 and 23 in the appropriate direction by means of themotor 35, and gearing previously described, will cause the 'pitmen, and consequently the plunger [bar and attached parts to ride upwardly on the screws. As the plunger bar emerges from the slotslfi and 17 it is engaged by the curved deflector arms or guides 57 and 58,

bolted to and projecting upwardly {and inwardly from the strips 53 and 54, and is thus thrown over to one side upon the curved tracks 59 and 60, secured to the upper ends jofthe end walls of the baling chamber. Further rotation of the screws causes the plunger bar to travel over the curved tracks 59 and until the pitmen 42 and 43 come in contact with the fulcrum blocksfil secured to certain of the guide strips 53 and 5%. As the nuts 51' andw52 continue to rise the pits men fulcrum on these blocks until a hori-' zontal or Figure 2. position is reached by the pitmen. at which point the power is cut off automatically by any suitable trip mechanism (not shown) or the power may be cut off manually in an obvious manner.

Whenthe pitmen reach a horizontal positionthe plate 39 and slats 40 assume a vertical position outside the chamber 6, and consequently permit of a charge of material beingfed therein at the top. It is also to be noted. that the curvature of the tracks 59 and 60 is such that the plunger bar at no point in its travel is self locking. Consequen'tly when the motor isrevcrsed and the screws rotated in a reverse direction to that just described, the plunger bar will be caused to ride back over the curved tracks until the plunger rod again enters the slots 16 and Having thus described our invention what we claim as our invention is: i 1. In a baling press, the combination with a chamber having an open end, of a platen movable transversely of said chamber beyond said open end'and also movable within said chamber, a screw rotatably connected to said platen for actuating the same, and a guide for automatically compelling said platen tomove transversely of said open end upon movement of said platen from within said chamber through said open end.

1 2. In a baling press, the combinatmn with a chamber having an open end, ofa platen movable transversely of said chamber beyond said ".opengcnd and also movable -within said chamber, a rotatablefscrew, a nut threadedrmpon said screw, means for pivotally connecting said platen to said nut, and means dependent upon the rotation of said screw for automatically compelling said platen to move laterally of said open end;

' 3. In'a baling press, the combination with a vertical baling chamberhaving anopen upper end, of vertical screwsat opposite ends of said baling chamber, a platen adapt ed to be raised and lowered within said chamber by said screws, and a guide for automatically compelling saidplatcn to move laterally over and beyond the upper endi of said chamber upon movement of said platen from within said chamber through said open end. i

4. In a baling press, the combinatimrwith i:

a chamber having anopen end, of a platen movable transversely of said chambcry beyond said open end and'als'o movablewith in said. chamber, a screw connected to said platen for actuating-thesame, and means for compelling said platen to move transversely of said chamber beyond said, open end to open position upon rotation of. said screw in one direction and to return into registration with said'open end upon rota-.

tion of said screw the opposite direction.

5. In a baling press, the combination, with a chamber having an open end, of a screw, and a platen connected to said screw and movable within said chamber and also auto:

matically movable transversely of "said chamber'beyond its open end. 6. In a baling press, the, combination with a chamber having an open,cnd,'of a screw and aplaten adapted to extend transversely of said chamber when in operative position and to extend approximately parallel to a wall of said chamber whenin inoperative,
